@rhpot1991, With xps 9300(icl), can't reproduce the issue. I plug one monitor on wd19tb and disable the screen lock.
please enable the drm debug with drm.debug=0x1e. reboot the machine and try reproduce it. Then dump "journalctl -k -b" Thanks -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1889342 Title: Thunderbolt Dock Loses Monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1889342/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
